Inventor: BEIDA RODNEY T
IPC: E21B36/00
Filed: 2002-11-28
Abstract: Apparatus and method for heating and preventing freeze-off of wellhead equipment utilize radiant heat from a flameless heater to heat fluid in a heat exchanger, such as a tank or finned radiator. A pump is used to circulate the heated fluid through a conduit loop deployed in thermal contact with the equipment to be heated, such that the heat from he fluid is transferred to the equipment, maintaining it at sufficient temperature to prevent freeze-off. The apparatus and method may also be used for other purposes, such as for circulating heated fluid through a liquid-cooled engine to facilitate cold weather starting.

Abstract: Afin de mieux comprendre l'angiogenèse tumorale, de nouvelles techniques permettant d'isoler des cellules endothéliales et d'évaluer des profils d'expression génique ont été développées. La comparaison effectuée entre des transcrits issus de cellules endothéliales provenant de tissus colorectaux normaux et malins et des transcrits issus de cellules non endothéliales a permis d'identifier plus de 170 gènes qui sont exprimés de manière prédominante dans l'endothélium. La comparaison entre des endothéliums d'origine normale et d'origine maligne a permis de mettre en évidence 79 gènes à expression différentielle, dont 46 étaient particulièrement élevés dans des endothéliums à association tumorale. Des expériences menées avec des gènes représentatifs de ce groupe ont montré que la plupart de ces gènes étaient exprimés de manière identique dans l'endothélium de cancers primitifs du poumon, du sein, du cerveau et du pancréas, ainsi que dans des lésions métastatiques du foie. Ces résultats montrent que l'endothélium néoplasique et l'endothélium normal sont distincts chez l'homme, au niveau moléculaire, et sont sensiblement impliqués dans le développement de futures thérapies anti-angiogéniques.

Patent CA-2419304-A1 (CA)
Title: Optical repolarizing devices
Inventor: LAUZON JOCELYN
IPC: G02B6/12
Filed: 2003-02-20
Abstract: An optical repolarizing device for transforming either a randomly polarized or unpolarized input beam into a polarized output beam. A polarization dependent beam splitter splits both polarization components of the incident signal and inserts them into an interferometer. In one arm of the interferometer, a polarization rotator, equivalent to a half waveplate, is inserted. In the other arm of the interferometer, a phase shifter is inserted. The phase shifter ensures that there are no delays between the signals in the two interferometer arms, and thus there is constructive interference when the two beams, now having the same polarization, recombine at the output of the interferometer, where a beam combiner is provided for this purpose. For unpolarized input light, the phase shifter is unnecessary.

Title: Gaming device having varying risk player selections
Inventor: PALMER GREGG J
IPC: G07F17/32
Filed: 2003-02-28
Abstract: The present invention provides a processor controlled gaming device having a display device in communication with the processor. When the display device receives an input from the player, gaming device 10 randomly generates an outcome, the display device displays an event having the outcome and gaming device 10 provides the player with a payout in association with the outcome and the selected input. The inputs have paytables that vary in range. One input has a large, risky payout range with big and small payouts. One input has a small, conservative payout range with intermediate payouts. Other inputs have ranges that fall in between the risky and conservative ranges. Each of the ranges has the same overall expected value, so that gaming device 10 does not favor the player's choice of a risky or conservative input.

Title: Matrix metalloproteinase inhibitors
Inventor: ROARK WILLIAM HOWARD
IPC: C07D487/04
Filed: 2002-02-13
Abstract: Compounds are provided that bind allosterically to the catalytic domain of MMP-13 and comprise a hydrophobic group, first and second hydrogen bond acceptors and at least one, and preferably both, of a third hydrogen bond acceptor and a second hydrophobic group. Cartesian coordinates for centroids of the above features are defined in the specification. When the ligand binds to MMP-13, the first, second and third (when present) hydrogen bond acceptors bond respectively with Thr245, Thr247 and Met 253, the first hydrophobic group locates within the S1' channel of MMP-13 and the second hydrophobic group (when present) is relatively open to solvent. The compounds specifically inhibit the matrix metalloproteinase-13 enzyme and thus are useful for treating diseases resulting from tissue breakdown, such as heart disease, multiple sclerosis, arthritis, atherosclerosis, and osteoporosis.

Abstract: An aluminum casting method includes the step of applying in advance a mold release agent including magnesium to a mold surface. Thereafter, a nitrogen gas is injected into a cavity to cause reaction between the magnesium in the surface of the mold release agent and the nitrogen gas, thereby forming magnesium nitride. Since the nitrogen gas reacts only with the magnesium exposed in the surface of the mold release agent, the forming time of the magnesium nitride is reduced and also the amount of nitrogen gas used is reduced.
